Answer:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
18% = 18/100 = 18 ÷ 100 = 0.18.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 18% of its value.
Percentage decrease = 18% × 328
New value = 328 - Percentage decrease
New value =
328 - Percentage decrease =
328 - (18% × 328) =
328 - 18% × 328 =
(1 - 18%) × 328 =
(100% - 18%) × 328 =
82% × 328 =
82 ÷ 100 × 328 =
82 × 328 ÷ 100 =
26,896 ÷ 100 =
268.96
